Letters Patent No. 86,616, dated Februu/ry 2, 1869.

STOVE-GRA'IE.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom it may concern Be it known that I, GEORGE A. Use, of Albany, in the county of Albany, and State of New York, have invented a new and improved Grate for Stoves and Furnaces; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanyin drawings, form a part of this specificatiom'aml to the letters of reference marked thereon, in which Figure 1 is a top view of my invention.

Figure 2 is a vertical central section, taken on a plane running from front to back.

Similar letters of reierence indicate like parts.

To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and mode of operation.

My invention consists in constructing a circular grate of two series of concentric rings or bars, the lower series stationary, and the upper series movable about a central pivot, D.

B" designates the lower series, or stationary series, of concentric rings. They are attached to and supported upon two intersecting cross-bars, c 0, running underneath them, as maybe seen in figs. l and 2.

The whole grate is supported and kept in'place by the lower cross-bars c 0, whose ends project in three points beyond the outer and lower concentric ring B as shown at 7t It 1:, in tig. 2. It will be seen, byinspection of this figure, that the grate may be dumped by depressing the shaker f.

B designates the upper series of concentric rings,

and having a rebate, g, on its. outer and top edge, by

which it may be suspended in any suitable-sized stove or furnace. Both sides of the two series of concentric rings are corrugated, as shown at u a, in fig. 2.

It will be seen fi'om the above description that the ring A, and on both sides ofthe two series of concentric rings B and B that all slag and clinker-s may be easily broken up by rotating the grate in the usual and well-known manner, by means of the shaluarf.

It will also be seen that this grate may be easily placed in any stove or furnace of suitable size, by first suspending the outer ring A within the fire-chamber of the same; and then the grate itself, by means of the cross-bars c 0, under its bottom, may be put into place within the ring A.

Having described my invention, and its mode of operation,

\Vhat I claim as new, and desire to-secure by Letters Patent, is-

1. The combination of the two series of ctmcentric rings, or grate-bars, B and B one series stationary. and the other movable, operating substantially as and for the purpose herein specified and shown.

2. In a circular grate, constructed of two series of concentric rings, B and B the construction oi'corrugations (6 a in the same, for the purpose of breaking up the clinkers or slags in the fire-chamber at the top of the grate, substantially as herein shown and described.

3. In a circular grate, constructed of two series of concentric rings, 13 and B", as herein described, the-employment-of an outside ring A, for sustaining the grate in the stove, in combination with the two sustaining cross-bars c c, underneath the stationary concentric rings Bflsubstantially as and for the purpose herein Set forth.

4. The movable corrugated centre 0, in combina tion with the movable concentric rings 13", and the cross-bars (l d, above the movable concentric rings B substantially as and for the purpose herein set forth.
